Additional information

Burning rate, solid:

According to REACH legislation, Annex VII, column II flammability does not need to be conducted since the substance is a liquid. Flammability for liquids is expressed as flash point.

Contact with water:

‘Polyether T 460' did not ignite spontaneously with water and did not liberate gases in hazardous amounts when tested according to EC Test Procedure A 12. The applied testing method is identical to the testing method with UN -Manual ‘Recommendations on the Transport of Dangerous Goods – Manual of Tests and Criteria’ (fourth revised edition) Test N.5 (UN 33.4.14).

With application of EC-Guideline 1272/2008 (Regulation on Classification, Labelling and Packaging of Substances and Mixtures, CLP) Annex 1, chapter 2.12 the criteria for classification ‘Polyether T 460’ as ‘substance which in contact with water emit flammable gases’ are not fulfilled.

Pyrophoric properties:

The molecular structure of the substance does not contain functional groups that might lead to pyrophoricity. Therefore it is considered justified to omit the study.
